Install SCAL-P

You have a few options to get SCAL-P on your machine.

Download a pre-built binary

The easiest way. Grab the latest release from the releases page.

curl -L https://github.com/scal-p-labs/SCAL-P/releases/latest/download/scalp_linux_amd64.tar.gz | tar xz
sudo mv scalp /usr/local/bin/

curl -L https://github.com/scal-p-labs/SCAL-P/releases/latest/download/scalp_darwin_amd64.tar.gz | tar xz
sudo mv scalp /usr/local/bin/

Install via Go

If you have Go 1.22+ installed:

go install github.com/scal-p-labs/SCAL-P/cmd/scalp@latest

Build from source

Requires Go 1.22+.

git clone https://github.com/scal-p-labs/SCAL-P
cd SCAL-P
make build

The binary lands at .bin/scal-p. Add it to your PATH or copy it:

sudo cp .bin/scal-p /usr/local/bin/

Verify the installation

scalp version

You should see something like:

scalp dev (none) 2026-05-22T00:00:00Z

Verify the binary integrity

If you downloaded a release, you can verify the binary hasn't been tampered with. SCAL-P's release pipeline generates checksums for every artifact:

# Download the checksums file alongside the binary
curl -L https://github.com/scal-p-labs/SCAL-P/releases/latest/download/checksums.txt > checksums.txt

# Verify the binary
scalp verify \
  --artifact scalp_linux_amd64.tar.gz \
  --checksum checksums.txt \
  --ci

Package manager detection

SCAL-P auto-detects your package manager from the lockfile:

If you have multiple lockfiles or none, use --pm to specify:

scalp install --pm yarn --guarded
